M20-9772142

Headers, Male Pins Overview

The Harwin M20-9772142 is a male pin header assembly from the M20 series, designed for board-to-board or cable connections. It features a 2-row configuration with 14 positions (7 per row) and a 2.54 mm pitch. The connector utilizes through-hole solder termination with right-angle mounting. Contact surfaces are gold-plated for reliable conductivity, while the tail contacts are tin-plated to facilitate soldering. The housing is constructed from black polyamide (PA6T), rated UL94 V-0, supporting an operating temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting design facilitates compact vertical board stacking.
• Gold-plated mating contacts ensure durable low-resistance signal transmission.
• Cuttable strip format allows for flexible position count customization.
• High-temperature resistant PA6T insulation supports demanding thermal environments.

Headers, Male Pins Applications

• Vertical board-to-board interconnects in industrial control modules
• Signal routing in telecommunications equipment backplanes
• Connection points within automotive electronic control units
• Interface assemblies in medical diagnostic instrumentation

Headers, Male Pins Procurement Notes

Verify the specific suffix code against the official Harwin datasheet to confirm contact plating and orientation specifications. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure that the right-angle footprint matches the target PCB layout dimensions. Check for any recent product change notifications regarding material substitutions or manufacturing site transfers.

Headers, Male Pins Selection Notes

Select this component when a right-angle, double-row header is required for space-constrained vertical stacking. The 2.54 mm pitch ensures compatibility with standard DIP components and ribbon cables. Verify that the current rating aligns with the application's electrical load requirements. Consider the cuttable nature of the strip if variable pin counts are needed across different production batches.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for their robust mechanical design and high reliability. The M20 series offers various configurations including single and double rows with both straight and right-angle options. This specific model represents the double-row, right-angle variant optimized for applications requiring vertical interconnection between printed circuit boards.

Headers, Male Pins Replacement Considerations

No direct public substitute part numbers are confirmed for this specific configuration. Evaluate other M20 series variants with matching pitch and row count if availability is critical. Cross-reference mechanical dimensions and electrical ratings before adopting alternative manufacturers' equivalents.
